Crystal International Group Limited has taken circularity to a new height by launching the eco denim collection – Second Life online. The collection adopts recycled denim fabrics and sustainable materials to minimize wastage and keep materials in use, achieving a circular denim business model.
The eco denim factory in China initiated the new concept – Second Life in 2020 and worked towards infusing pre-consumer cut waste and sorted scraps with a new life. By reducing the use of new materials, Crystal Denim can reduce water and energy consumption from growing new cotton, which accounts for around 70% of water consumption and 10% of carbon emission throughout the product life cycle of denim jeans. By collaborating with the partnering mills, Crystal Denim has successfully developed 10 denim fabrics for men’s and women’s collections. Compared with the traditional recycled denim fabrics, the fabrics of Second Life collection can provide greater depth of color shade and stronger intensity of weft yarn while maintaining durability. The variety of colors does not necessarily have to be sacrificed when using recycled materials. 10 fabrics are also different in recycled content, elasticity, and stretchability. With more choices of color shade and different washing effects, the fabrics can create both dark and light colors, thus offering more styles and widening the product range. The collection goes for a vintage look to embrace denim authenticity. All fabrics are launched with the physical and digital format, and benefit product development including 3D virtual sampling.
“The collection goes beyond “Second Life” and extends the circularity to even “Third Life” by further regenerating the wastage from the circular fabrics to other denim items. The cut waste from Second Life denim is gathered and upcycled as the new kimono jackets, patches, and accessories to work towards zero wastage”, said Mr Miles Lam, Assistant General Manager of Product Development of Crystal Denim.
The Second Life collection utilizes recycled cotton which is dyed with liquid indigo for further water and chemical reduction. Some key wastewater parameters such as chemical oxygen demand COD and total suspended solids can be reduced by over 60%. Recycled denim fabrics can mitigate the environmental footprint of virgin denim fabrics production, particularly water consumption. Eco washing methods are adopted in the finishing approaches without manual labor work. The whole collection of closed-loop denim made by recycled fabrics is certified with Recycled Claim Standard (RCS), as well as sustainable materials including Lycra T400 fiber with EcoMade technology and REPREVE recycled polyester. With the chain of custody standards, certified materials are traceable along the supply chain.
